With most telescopes you can often see some objects in the sky better with lower power and a wider field of view. You can increase the true field of view of your telescope and lower the power, which makes finding objects easier, with the Orion 2" Telescope Accessory Kit! This assortment of a carrying case with pluckable foam (so you can sort your accessories any way you desire), 3 DeepView eyepieces, an Orion 2" Barlow lens and a 2" Orion SkyGlow filter gives you a perfect introduction to the advantages of 2" eyepieces for deep-sky viewing.

The eyepieces in this kit include the Orion 42mm, 35mm, and 28mm focal length DeepView models which are optimized for bright, low power, wide fields of view. The included 2", 2x Barlow lens allows you to double the magnification of any of the three included eyepieces, allowing you to achieve a total of 6 possible magnification options (resulting magnification of each eyepiece and Barlow/eyepiece combination depends on the focal length of your telescope). The 2" Barlow is threaded for use with big 2" eyepiece filters. We've also included a 2" SkyGlow Broadband Filter which will help combat the ill effects of light pollution, and help optimize your wide-field observations.

Remember, while 2" eyepieces have definite advantages for deep sky observers, you must have a telescope focuser with a 2" holder that will accept 2" eyepieces - these usually come standard on an 8" or larger diameter telescopes.

The Orion 2" Telescope Accessory Kit includes:

42mm Orion 2" DeepView Telescope Eyepiece

35mm Orion 2" DeepView Telescope Eyepiece

28mm Orion 2" DeepView Telescope Eyepiece

2" Orion SkyGlow Broadband Eyepiece Filter

2" Orion 2x Barlow Lens

Orion Pluck-Foam Accessory Case

The included carry case measures 17.5" x 13.5" x 6" and has a pluck-foam interior so you can choose exactly how you want to arrange your eyepieces and accessories inside. This 2" kit of accessories is a great introduction to the joys of using low-power and wide field of view eyepieces with your telescope that will take your observing sessions to a new dimension. It's a must-buy for anyone interested in exploring deep-sky objects!

Design

Different eyepiece designs allow for a wide range of features, depending on the needs of the observer. Orthoscopic and Plossl designs can provide a great quality image with a standard field of view, but may be difficult to use at higher powers while wearing glasses due to the short eye-relief. Long eye-relief designs have more elements and can be more expensive, but work very well with glasses, even at higher powers. Wide angle designs provide a larger view of the sky at the same power as a standard eyepiece. More complex designs can combine all these attributes together in a single eyepiece.

Apparent field of view

The edge-to-edge angular diameter of the image displayed in a binocular as seen by the eyes of the observer. It is an inherent specification for a given binocular design. The "angular diameter" of an object is defined as the angle an object makes (subtends) as seen by an observer.

Eye relief

The distance, measured in millimeters, between the observer's eye and the eyepiece lens in which the entire field of view remains visible. Eye relief varies with the optical design but generally increases with decreasing magnification. Long eye relief is advantageous for observers who wear glasses, as they don't have to put their eye directly on the eyepiece to see the entire field of view, nor do they have to remove their eyewear.

Coatings

Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.

Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.

Parfocal

Barrel security recess

The barrel security recess is a shallow groove or depression cut into the 1.25" or 2" barrel of the eyepiece. In the event the thumb screw holding the eyepiece in the focuser becomes slightly loose, the eyepiece will not fall out because the tip of the thumb screw will catch on the lip of the security groove.

You've just bought your first telescope, but now what? The Orion Beginning Stargazer's Toolkit is the perfect addition! This best selling kit includes a planisphere star atlas, Discover the Stars book, Orion MoonMap 260, and a red flashlight.

The Orion 2" 13% Transmission Telescope Moon Filter reduces the glare from the moon so you can see more detail and surface features. This filter is especially useful in large-aperture telescopes since the moon's brightness can be overwhelming.
